Title: Apparatus for recording printed characters
Inventor: MASON FREDERICK PERCIVAL
IPC: B41J2/465
Filed: 1967-12-15
Abstract: 1,149,448. Recording devices. CREED & CO. Ltd. 15 Dec., 1967, No. 56995/67. Heading G4H. Input signals 17 (Fig. 2), each representing one character of a line of text to be recorded, are compared with signals 16 representing the rotational position of e.g. a drum 1 (Fig 1), having a matrix 2 of characters which transmit or reflect light, all characters in a row being identical, a shutter 6 being operated when the signals to its associated comparator 15 (Fig. 2) are identical so that the character then in front of the shutter is recorded on a surface 7 (Fig. 1) which may be frosted or fluorescent screen or photographic or xerographic material. All identical characters in a line are recorded simultaneously, a line of text being recorded for each rotation of the drum. The signals representing the position of the drum are derived from binary coded markings 12 around the circumference of the drum. Instead of recording on a surface, the line of text may be viewed on the surface of the drum through the shutters.

Abstract: 1461415 Electron beam furnaces GENERAL ELECTRIC CO Ltd 9 Dec 1974 [12 Dec 1973] 57568/73 Heading H1D A glow discharge electron gun, e.g. for electron beam heating apparatus, having an anode structure with a generally planar, apertured first surface facing the cathode 13 and spaced from it a distance less than the minumum at which a gaseous discharge can occur between them, and a second surface 16 defining, on the side of the aperture remote from the cathode, a volume through which the beam passes in operation, having a cross-sectional shape, at least at its end adjacent the aperture, corresponding to that of the aperture, and extending along the beam path for a distance not less than the minimum width of the aperture, which is preferably not less than 8 mm., the dimensions of the aperture and volume being such that, for a range of anode to cathode operating voltages the boundary of the plasma 26 is crossed by the electron beam within the volume, whereby variation of focusing with beam current is minimized. As described, the first and second anode surfaces are provided by different parts 15 and 16 of the same anode which is supported by a metal tube 14 surrounding the aluminium rod cathode 12, the metal supporting plates 7 and 9 being insulated from one another by insulators 6 and 8, to which they are sealed by 0-rings 11. The chamber 3 is continuously evacuated via an aperture in the support tube 2 for the work-table 1, and argon is admitted via the port 10 in metal wall 4 to maintain a pressure of 0À1 torr. Tube 16 may have an internal diameter of 15 mms. and a length of 30 mms., the beam current arising both from secondary emission at the cathode due to ion bombardment, and also from the hollow cathode effect produced when the anode is maintained negative with respect to the worktable 1; the latter effect produces partial compensation for the charge of beam current with gas pressure arising from change of temperature during operation. The anode structure may comprise more than one anode, permitting the first and second surfaces to be held at different potentials, and the beam may be of pencil, annular, or rectangular shape. It is stated that a desired variation of focus with beam current may be achieved by suitably varying the crosssection of tube 16 along its length.

Title: Non-volatile memory cell

Filed: 1973-12-12
Abstract: 1461085 Memory IGFET TEXAS INSTRUMENTS Inc 12 Dec 1973 57587/73 Heading H1K A non-volatile reprogrammable memory device comprises a semi-conductor substrate or region of one conductivity type, source and drain regions in its surface forming PN junctions therewith, a floating gate conductor extending between these regions on an insulating layer and means including a further PN junction or specially adapted parts of the source and drain junctions disposed beneath the gate or an extension thereof for producing hot electrons or holes for transfer to the gate conductor through adjacent portions of the insulating layer which preferentially conduct holes and electrons respectively. In the device shown in Fig. 5 zones 52, 54 form with N+ regions 60<SP>1</SP>, or with a single N+ region extending between them, avalanching junctions located respectively beneath thin insulation 55, e.g. silicon nitride, pervious only to hot holes and 58<SP>1</SP>, e.g. silicon oxide pervious only to hot electrons and also constitute the source and drain zones respectively of an IGFET gated by the rear portion of conductive layer 56. To write in logic "1" the drain junction is biased to avalanche breakdown to produce hot electrons which traverse insulation 58<SP>1</SP> to negatively charge the gate and switch on the IGFET. Logic "0" is written by biasing the source junction to avalanche breakdown to generate holes which pass through the insulation 55 to positively charge the gate to switch the IGFET off. Electrodes are provided on the source, drain and substrate region for this purpose. In a modified device each of the zones 52 and 54 is replaced by two separately contacted zones which respectively perform the source (or drain) and hole (or electron) injection function. Sometimes the electron injection function can be performed by the drain junction proper instead by the separate electron injection zone.
